Title: Stack setting machine feed mechanism - has two pneumatic valves for stack positioning and advancing to setting gun
Inventor: RIPAMONTI MARIO
IPC: B27F7/13
Filed: 1980-07-25
Abstract: The stacks are indexed individually by a lever (12) with one arm carrying out the pushing movement, the other arm connected to the rod (15a) of a pneumatic cylinder. The cylinder is supplied with air from a three-way valve (18), operated pneumatically through a connection (20) carrying part of the waste air of the setting gun. A branch line (21) runs parallel to the connection (16) of the cylinder. The branch controls, via a delaying element (32), a second three-way valve (33) connected to the compressed air source. The valve is controlled by air from the branch piping (21) and the delaying element (32), causing admission of compressed air into a line (34) which advances a stack into the transport hose.

Title: Microwave hardening of synthetic resins - coated on metal parts, e.g. oil-free satd. or oil-modified unsatd. polyester(s)
Inventor: SIMONIAN JOHN LAWRENCE
IPC: C08L67/00
Filed: 1980-10-03
Abstract: Microwaves are used for hardening synthetic resins applied on metal parts present as a reel, esp. Cu reels, or as metal laminates enclosing a dielectric. Wire reel exposure to microwaves is also claimed, to soften a coating which bonds the reel wires. The reel wires pref. consist of Cu coated with a wire-lacquer and with a thermoplastic top-coat. The metal parts can be armature controls, stators, transformers, and magnetic reels. Microwaves impinging on a part are effectively converted to heat. Resin hardening time is shortened, e.g. to 15 min. as opposed to 1 hr on using electrically heated hot air. Energy consumption and costs are reduced.

Title: Self-elevating hopper for building construction - uses lifting gear in lateral deployment of four telescopic props by sliding rotation and articulation
IPC: B65D90/14
Filed: 1980-10-15
Abstract: The self-elevating hopper uses lifting gear which effects the lateral deployment of four telescopic props. Elevation of the hopper entails sliding, rotation or articulation of the props, these three movements being used simultaneously as a group or in pairs. The functional hopper has good stability with a minimum prop speed of three metres, and the props retract to provide a highway transit gauge of less than 2.4 metres. The system may be used to secure the unit on a carrier vehicle, lowering the centre of gravity and reducing sway. The dead weight of the unit may be one quarter of its total loaded weight and the lifting gear may be driven by cable, rack or jack.

Abstract: Method for mfg. tiles with an aged appearance is described in which, immediately after leaving the extruder, the extrudate is given a surface scratching then cut into tiles which are then coated with a clay slurry and a granular prod. is sprinkled onto the slurry before firing. The slurry and granular coatings may be repeated before firing. The tiles can be made directly to have the same appearance as tiles which have been on buildings for a century or more, and hence be suitable to replace existing tiles or to reroof old buildings.

Title: Method of making key for opening food tin - uses lengthwise oblique cut in stem followed by splitting stem and twisting half stem sideways
Inventor: GOURHANT MICHEL
IPC: B21F45/00
Filed: 1981-03-25
Abstract: The process is used to fabricate a key which opens a food tin by winding a strip out of the wall of the tin. A longitudinal slanted cut (3) is made in a piece of metal wire (1), a cutting-stamping tool then being used to split the wire by twisting a half of the wire (4) laterally over a pre-determined length. Finally the twisted half is re-positioned on the wire axis (x-x) defining a narrow crevice (5) into which the tongue of a tin is introduced. The crevice may reduce in width uniformly from its inlet to its bottom (5a).

Title: Optical missile guidance system - has piezoelectric vibrating mirror to control beam position oscillating about axis to be followed by missile to produce interference fringe
Inventor: CHABANNES FRANCOIS
IPC: F41G7/26
Filed: 1981-04-10
Abstract: The system uses a beam of laser light which is periodically oscillated by the source through a small angle about the axis along which the missile is guided. A laser generator (1) emits a beam (2) towards an optical system (3) which includes two identical plane mirrors (4) situated side by side in the same plane. The first mirror is glued to the metal support (7). The second mirror (5) is attached to one electrode (8) forming the upper surface of a piezoelectric element (9). The piezoelectric element has a second, lower electrode (10), by which is attached to the support (7). The terminals of an alternating supply signal generator (11) are connected to the two electrodes of the piezoelectric element. A photoelectric detector on the missile responds to the interference fringes produced by the two beams and the information is used for guidance.

Patent FR-2500081-A1 (FR)
Inventor: SCHULZE ECKEHART
IPC: F04B9/08
Filed: 1982-02-16
Abstract: In the case of a dosing pump (metering pump) which is designed to deliver liquid media and which, for example for chemical processes, performs computer-controlled dosing, speed and/or piston travel being controllable, it is proposed to effect the drive for the piston (4, 4') of the pump (1, 1') via at least one hydraulically or pneumatically actuated working cylinder (2, 2'), said working cylinder(s) (2, 2') being controllable, in terms of lift and lifting speed, via an electronic controller (10), the piston velocity and the piston travel being preset to this end via an electronically controlled stepping motor (11) and being adjustable via a servo-control (9) with an actual-value feedback (8). This enables movement, very largely independent of the mechanical construction, of the pistons (4, 4') of the pump (1, 1') of the dosing pump, which can be matched, without any mechanical modification, to different flow media, delivery rates and time-dependent delivery profiles. If required, a plurality of dosing pumps of this type can be connected in parallel or in series.
